I hope the link to my video works now. Here's an update. I took the ignition and fuel pump relay out again and had my wife turn it over while I looked at the flexplate through the hole and behind the plastic starter cover. Looked fine, so I watched the top of the motor while she cranked it and everything looked fine. I put the ignition relay back in and had her start it with the remaining fuel in the rails and it sounded like the noise was coming from up top. I wanted to rule out any acccesory noise so I took the serp belt off then cranked it. It immediately made a huge bang and smoke was everywhere. I see that it blew the valve cover gaskets out, litterally out, and there was plenty of smoke coming from underneath as well, so I suspect maybe the pan gaskets blew out as well.? I'm going to pull it apart now, but I suspect I'll be needing a new motor...
